What is Meningioma?

Meningioma meaning Memingiomas, a type of neuroepitheliomatous neoplasms, arise in the meninges, the membranes that envelop the brain and spinal cord: dura mater, pia mater, and arachnoid. These are slow growing tumors and are most always benign. They are rare in children. Meningiomas tend to occur along the superior sagittal sinus, along the sphenoid ridge or in the vicinity of the optic chiasm.
